Description

[Detailed description of the invention] The present invention relates to an electromagnetic relay.

In conventional electromagnetic relays, a terminal block with terminal groups implanted on both sides of a coil block is joined, but one assembly is complicated, and when soldering the terminal groups, solder flux etc. is removed from the joint surface etc. was flowing in, causing poor contact at the contacts.

Furthermore, since other members are assembled using the coil block as a base, if the coil frame is deformed when the coil is wound around the coil frame, distortion will occur throughout the coil frame.

Accuracy was difficult to obtain.

The present invention aims to eliminate the above-mentioned drawbacks, provide an electromagnetic relay that is easy to assemble, prevents the inflow of solder flux, and has high precision.

The invention will now be explained with reference to the figures.

In the figure, reference numeral 1 denotes a coil block around which a coil 4 is wound.A coil frame 21/c holds an iron core protruding from both ends as magnetic poles 3.3.

- Also, on the upper surface of both ends of the support frame 2, the ends of the lead wire of the coil 4 are connected, and coil lead-out terminals 5 whose tips are bent into an L-shape
, 5 are extended, and engaging protrusions 6 are provided on both sides, respectively.
, 6 are provided.

Reference numerals 7 and 7 denote contact blocks that are joined from both sides of the coil block 1, and contact terminals 8 and 8 protrude from the upper and lower surfaces, respectively.
, 9.9 are molded at the same time, and a coil terminal 10.10 is molded at the same time, with both ends cut out and the upper end 11.11 bent so as to extend in a direction perpendicular to the longitudinal direction.

The upper end portions 11.11 of the coil terminals IL) and 10 are provided so as to be able to contact and be welded to the ends of the coil lead-out terminals 5 and 5.

Also, the contact terminals 8.8, 9 of the contact block 7.7
．． 9 and the downwardly protruding ends of the coil terminals io, io are aligned in a line, and the engaging protrusion 6. , 6 are formed therein.

13 is a box-shaped base block with the contact terminal 8 on the bottom surface.
, 8, 9.9 and a group of 14 holes into which the lower ends of the coil terminals 10.10 can penetrate are formed in two rows on both sides,
Moreover, it is formed so that a joined body of the coil block 1 and the contact block 7.7 can be inserted therein.

15. 15 is a contact spring whose base is bent into an L-shape and is fixed inside the center contact terminals 8, 8.

9. The movable contact at the end is fixed. It extends so as to be able to contact the contact terminals 9 near both ends.

16.16 is a plate spring whose one end is fixed to the contact terminals 8, 8 together with the contact spring 15.15; 17 is a notch 18, 1 corresponding to the magnetic pole 3, 3 protruding from the coil block 1;
8 is formed on the separator.

A shaft 19 is installed in the center.

Reference numeral 20 designates an armature block in which a pair of armatures 21 and 21 are arranged parallel to each other, a bearing piece 22 is provided with a shaft hole 23 through which the shaft 19 is inserted, and the bearing piece 220 has a bearing piece 22 on both sides thereof. A card part 24.24 is integrated, which is spaced apart from the part 22 and which projects outwardly at right angles to the longitudinal direction of the armature 21.21 and can press against the contact spring 15.15.

Further, the protruding ends on both sides of the armature 21.21 are provided to play with the magnetic poles 3, 3.

25° 25 is a concave portion 26, 26 sandwiching the bearing piece 22.
The permanent magnet 27 housed in is a cover having a receiving portion 28 for the shaft 19 formed on the inner wall of the upper surface thereof, and is brought into contact with and fixed to the upper part of the base block.

Therefore, from both sides of the coil block 1, the contact block 1,
1 are joined, the lower ends of the contact terminals 8, 8, 9.9 and the coil terminal 10.10 are inserted through the hole group 14, and fitted into the base block 13, and the contact springs 15, 15. Separator 17. By mounting a group of contact opening/closing members consisting of an armature block 20 and mounting a cover 27 on top, an electromagnetic relay can be assembled by simply stacking them from one direction.

In this case, the adhesive may flow into the base block from above the coil block 1.

According to the electromagnetic relay of the present invention configured as described above.

a. It is easy to assemble by simply stacking the base block as a base. Since the I-shaped group is fitted into the hole group of the base block, it is possible to prevent solder flux from flowing in. C. west,
Moreover, since the coil block and the contact block are integrated and fitted, it is possible to assemble with high precision and reliability is improved.

and other remarkable effects can be achieved.
